Reply to "shiffter indent?"

To the last post, -probably not". Gear-grinding is usually caused by the clutch not fully releasing, which causes drag on the gear synchronizers inside the ZF. The stock clutch hydraulics were marginal when brand new and decades of wear makes it that much worse. Worn synchronizer rings in the ZF is extremely common and often costs around $1000-1500 to correct, as metal is worn away. The absolute best thing you can install is a long-throw stainless steel slave cylinder, to increase the separation of cluch & flywheel. Then use a full stroke of the clutch pedal when shifting.
